Baptism, the Eucharist, and the sacrament of Confirmation together constitute the “sacraments of Christian initiation,” whose unity must be safeguarded. It must be explained to the faithful that the reception of the sacrament of Confirmation is necessary for the completion of baptismal grace.89 For “by the sacrament of Confirmation, [the baptized] are more perfectly bound to the Church and are enriched with a special strength of the Holy Spirit. Hence they are, as true witnesses of Christ, more strictly obliged to spread and defend the faith by word and deed.CCC 125
In the sacrament of Baptism, a character, or mark, is placed on our soul allowing us to partake in the sacramental life of the Church. We are literally, marked for Christ. In the sacrament of Confirmation, we receive a second character that makes us sharers in Christ’s prophetic role as teacher and preacher. We are to then go out and preach the Gospel with our lives.
